Answer:

1/12

Step-by-step explanation:

First, 2/3 is less than 3/4

So, you have to subtract 2/3 from 3/4

2/3-3/4

To do the equation above, make the denominator common in both

2/3 × 4/4 = 8/12

3/4 × 3/3 = 9/12

Now you are able to subtract

9/12 - 8/12 = 1/12

_________________________

                         2/3      3/4

                         8/12    9/12

The solution is, 1/12 is the  fraction of the length of the pole is between Annie and Bolu.

Given a triangle XYZ on the graph

The coordinates of points X, Y and Z are

To find the approximate length of the sides, we apply the formula to find the distance, d, between two points which is

To find the approximate length of side XY, substitute the coordinates of points X and Y into the formula to find the distance, d, between two points

Hence, the approximate length of side XY is 3.16 units (option b)

i. Line BD = 6√2 cm

ii. Perimeter = 3 (π + 4) cm

iii. Area = 18 ( π - 2) cm

Let the length of BD = x

Since B is the midpoint of the arc AC, then ∠BOC = 15°

In ΔBDB

Let's use the trigonometric ration, tan

\(Tan 45 = \frac{BD}{CD}\)

CD = x

Then, using the Pythagorean theorem

\(x^2 + x^2 = 12^2\)

\(2x^2 = 144\)

\(x^2 = \frac{144}{2}\)

\(x = \sqrt{72}\)

\(x = \sqrt{36 *2}\)

\(x = 6\sqrt{2}\)

Thus, line BD is \(6\sqrt{2}\) cm

ii. Perimeter = BC + BD + CD

= 2πr/8 + x + r -  x

= π(12)/4 + r

= 3π + 12

= 3 ( π + 4) cm

iii. Area of shaded area = Area of BOC + Area of BOD

⇒ πr^2/8 × 1/2x^2

= π144/8 × 1/2(72)

= 18π - 36

= 18 ( π - 2) cm²

Great Songs will be the better deal after 100 songs.

Mathematical operations can also be defined by using built-in functions to subtract, divide, and multiply. The arithmetic operator is the one who conducts the arithmetic operation.

* Multiplication procedure: Values on both sides of the operator are multiplied.

For instance, 4/2 = 2

MyTunes imposes a fee of $2.50 per song. Great Songs charges $1.50 for each song and includes a $50 one-time membership fee, as stated in the question.

Let the songs that come after Great Songs would be x, the better the deal.

⇒ 2.50x = 1.50x + 50

⇒ 0.50x = 50

Divided by 0.50 into both sides of the equation,

⇒ x = 100

Step-by-step explanation:

it takes 2 seconds for the coconut to fall 64 feet.

To determine how many seconds it takes for the coconut to fall 64 feet, we can set up the equation y = \(16t^2\) and solve for t when y = 64.

The equation can be rewritten as:

\(16t^2 = 64\)

Dividing both sides by 16:

\(t^2 = 4\)

Taking the square root of both sides:

t = ±2

Since time cannot be negative in this context, we take the positive value:

t = 2

Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.

Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.

The total amount of paint needed is 3 gallons, so we have the equation:

x + y = 3

The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:

(80/100)x + (30/100)y = (50/100)(x + y)

Simplifying this equation, we get:

0.8x + 0.3y = 0.5(x + y)

Now, we can solve this system of equations to find the values of x and y.

Let's multiply both sides of the first equation by 0.3 to eliminate decimals:

0.3x + 0.3y = 0.3(3)

0.3x + 0.3y = 0.9

Now we can subtract the second equation from this equation:

(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)

-0.5x = 0.9 - 0.5x - 0.5y

Simplifying further, we have:

-0.5x = 0.9 - 0.5x - 0.5y

Now, rearrange the equation to isolate y:

0.5x - 0.5y = 0.9 - 0.5x

Next, divide through by -0.5:

x - y = -1.8 + x

Canceling out the x terms, we get:

-y = -1.8

Finally, solve for y:

y = 1.8

Substitute this value of y back into the first equation to solve for x:

x + 1.8 = 3

x = 3 - 1.8

x = 1.2

Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

The true statement about the function is that (c) the domain of f(x) consists of all values of x such that g(x) does not equal 0 and h(x) does not equal 0.

The complete question is added at the end of this solution

From the complete question, we have the following equation

f(x) = g(x)/h(x)

The above equation means that

The function f(x) is the quotient of the functions g(x) and h(x)

For the function f(x) to have real values, the function h(x) must not equal 0

i.e. h(x) ≠ 0

This is so because

A number or an expression divided by 0 is not a real number

The volume V of the solid is \(\left(0,\:\sqrt{\frac{65}{16}}\right)V+C\)

To find the volume of the solid obtained by rotating the region bounded by the curves y = 15x^2 and y = 65 - x^2 about the x-axis, we can use the method of cylindrical shells.

First, let's find the points of intersection between the two curves. Setting them equal to each other, we have:

15x^2 = 65 - x^2

Combining like terms, we get:

16x^2 = 65

Simplifying further, we find:

x^2 = 65/16

Taking the square root of both sides, we get:

x = ±√(65/16)

Since we are rotating about the x-axis, we only need to consider the positive square root, which is approximately 1.539.

Next, we need to find the height of each cylindrical shell. The height can be calculated as the difference between the two curves at a given x-value. So, the height h is:

h = (65 - x^2) - 15x^2
  = 65 - 16x^2

Now, we can set up the integral to find the volume V:

V = ∫[a,b] 2πrh dx

where a is 0 (the starting point) and b is the positive square root of 65/16 (the ending point).

V = ∫[0,√(65/16)] 2π(65 - 16x^2) dx

The explicit formula for a geometric sequence is

where a₁ is the first term and r the common ratio

Here a₁ = - 1 and r = \(\frac{a_{2} }{a_{1} }\) = \(\frac{-5}{-1}\) = 5 , then

\(a_{n}\) = - \(5^{n-1}\)

The length of side x is approximately 11.6622.

To find the length of side x in the triangle, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of its opposite angle is constant. In this case, we have the following information:

Side opposite angle 33°: 29

Side opposite angle 20°: x

Using the Law of Sines, we can set up the following proportion:

x / sin(20°) = 29 / sin(33°)

To find the length of x, we can rearrange the equation:

x = (29 * sin(20°)) / sin(33°)

Let's calculate the value of x using this formula:

x = (29 * sin(20°)) / sin(33°)

x ≈ 11.6622

If per capita energy consumption is approximately 3.5 × 108 BTU for US population of 325 million people , the energy the entire population consume is 1.14 × 1016 BTU. The correct answer is (d).

The United States has a population of approximately 325 million people. To estimate the total energy consumption for the entire population, we need to multiply the per capita energy consumption by the total number of people.

The per capita energy consumption is given as 3.5 × 108 BTU, which means that on average, each person in the US consumes 3.5 × 108 BTU of energy. By multiplying this value by the total population, we can estimate the total energy consumption for the entire population.

The calculation can be done by multiplying the per capita energy consumption by the population:

Per capita energy consumption (E): 3.5 × 108 BTU

Population (P): 325 million

Total energy consumption (T) = E × P

To calculate T, we need to multiply E and P:

3.5 × 108 BTU × 325 million = 1.14 × 1016 BTU

The total energy consumption for the entire population is 1.14 × 1016 BTU
